NOTE TO WEB MANAGER ABOUT GOOGLE CALENDAR:
Right now, there is a generic DCPS School Calendar.
To replace the calendar to the right with your own custom one that you control, you need to set up a Google Calendar.
To do so, go to "Calendar" link in top left. Create your calendar and makes sure you set it to share with the public.
Then come back to the calendar and click on the widget to the right. Go to Properties and select your new calendar.
